摘要
输电线路发生故障后，故障点将产生向变电站母线运动的行波，采集、记录在母线处测量到的故障电流行波波形，使用合适的算法，可实现输电线路精确故障测距。基于上述原理而研制的输电线路故障测距装置ＸＣ－１１，已在德州电网投入试运行。运行结果表明此装置具有很高的测距精度。
As soon as a transmission line fault happens, the travelling waves of transient current which move from the faulty position towards the bus at substation will immediately appear in the faulty line. Collecting and recording the data of travelling waves of the transient current, then using appropriate algorithm to calculate and analyze the collected data, the precise fault location for the transmission line can be realized. Based on the above mentioned principle, a protective relaying device XC-11 has been developed and put to use in Dezhou Power Network. The result shows that this device is of high precision.
